IMO, for the guys that liked to buy big guns and shoot them little, I suppose the 300 Ultra stole some of the SEVENMAG's thunder a few years ago.
But I don't see many new 300 Ultras around these days.
7mm Rem Mag is one of the rounds I shoot/hunt with the least. I usually hit right on either side of it (7 STW or 280).
But I would probably be the last to go if I had to start selling.
When properly hand loaded, it is uber versatile.
I think that the bigger mags like the 7 STW and Utras did steal some thunder from the 7 RM. I am starting to see more "traditional" cartridges along the lines of .270/.30-06. Maybe people realized that they didn't need that much range. Maybe the realized that they shot better with something that kicked less. Maybe the cost of ammo played into it, I don't know that I have a answer for sure
